: Distributing traffic to prevent single points of failure.
The most critical limitation is the absence of hands-on depth. The PDF can explain consistent hashing in a paragraph, but explaining why a consistent hashing ring handles node failures more gracefully than modulo hashing—and diagramming it on a whiteboard—requires genuine understanding. Interviews have shifted toward testing depth: follow-up questions might include “How would you handle leader election during a network partition?” or “What happens when your write-ahead log fills up?” The PDF’s summary answers will not suffice without studying the underlying consensus protocols (Raft, Paxos) or storage engines (LSM trees, B-trees).
